Study of High-Energy Antineutrino-Proton Interactions

Abstract

In an exposure of the Fermilab 15-ft hydrogen bubble chamber to a broad-band $\overline{\nu }$ beam, we have observed 106 $\overline{\nu }p\to {\mu }^{+}X$ events with a mean incident energy of 23 GeV. The experimental distributions agree well with the predictions of the quark-parton model. No anomaly is observed in strange-particle production.
